If you are often disappointed in the movies you have watched after reading the book , go the other way around. Reading the book after watching the movie is good too. It’s up to you. Whatever your decision, be aware that every movie ever made has been written first, at least as a script, and a vast amount of those scripts are inspired by books. So, if you like movies, you also like books. It’s logical right? Then, read one of those marvelous books already adapted into a movie or that will get a shot on the big screen soon.
